B-LINE P3BHJD3070 – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BHJD3070 plug-in unit carry?
The P3BHJD3070 is a 70 amp plug-in unit built on a J frame breaker, which covers the 70 to 225 amp range. So 70A is the bottom of that frame size, meaning the housing and bus stabs are sized for the larger J frame family even though the trip is set at 70 amps.
2) Will a 70A Pow-R-Way III plug-in unit hold up on a 480V distribution system?
Yes. The interrupting rating is 100 kAIC at 240 Vac, 65 kAIC at 480 Vac and 25 kAIC at 600 Vac, so it can be applied at 480V as long as the available fault current at that busway tap is at or below 65 kA. On a 600V system you are limited to 25 kA, which is where engineers most often find this unit under-rated for their calculated fault duty.
3) What clearance do I need on the busway run for the P3BHJD3070 plug-in unit?
The unit measures 23.26 by 12.36 by 6.97 inches. Lay those out against your busway elevation before you commit a tap location: the long dimension governs how much straight run you need between fittings, and the depth decides whether the unit clears adjacent pipe, duct, or a wall it is running tight to. Working space in front of the unit still has to be kept clear per code for the operating handle.
4) Can I use this plug-in unit on any brand of busway?
No. This is an Eaton Pow-R-Way III plug-in unit, and plug-in units are specific to the busway system they stab into. It belongs on a Pow-R-Way III run. If the busway overhead is another manufacturer's product, or an earlier Pow-R-Way generation, you need the plug-in unit built for that system instead.
5) How heavy is a Pow-R-Way III J frame plug-in unit, and can one electrician hang it alone?
It weighs 47 pounds. That is a two-person lift on a ladder or lift platform when you are engaging the stabs into an overhead busway run, and most crews stage it on a material lift rather than hand it up.
6) What part number do I quote for a 70 amp Pow-R-Way III breaker plug-in?
P3BHJD3070 is the number to quote, a B-Line branded Eaton Pow-R-Way III plug-in unit with a J frame breaker set at 70 amps. The P3 prefix identifies the Pow-R-Way III system, the J the frame class, and the trailing 070 the amperage.
7) I need to feed a 70 amp panel off overhead busway. Is a breaker plug-in unit the right approach?
For a fixed load or a downstream panel fed from an existing Pow-R-Way III run, a breaker plug-in unit like the P3BHJD3070 is the standard approach: it taps the bus and provides the overcurrent device and disconnecting means in one enclosure at the point of use, so you are not running a long feeder back to a switchboard. At 70 amps on a J frame, it suits a subpanel, a packaged mechanical unit, or a machine feeder. If you only need a receptacle drop or a cord-connected tool circuit, a smaller fusible or receptacle-type plug-in unit is the lighter and simpler choice.
